CENTRIFUGAL BASKET.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed August 2, 1921. Serial No. 489,242.

To all whom it may concern:

Be it known that I, EMERY E. LA DUKE, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in CentrifugalBaskets, of which the following is a specification.

My invention relates to centrifugal baskets, and has for its object toprovide a basket to be rapidly rotated on its vertical axis wherebyliquid may be strained and clarified of dirt and other similarsubstances by centrifugal force, and the claixified liqu d drawn off foruse, and particularly to strain and clarify gasolene and other cleaningfluids commonly used to clean articles of clothing, and also to clarifythe gasolene and other liquids used in garages in washing machinery andother parts of automobiles 1n making repairs. 7

These and other objects which Wlll be apparent I accomplish with thedevice illustrated in the accompanying drawings, in which similarletters and numerals of reference indicate like parts throughout theseveral views, and as described in the specification forming a part ofthis application and pointed out in the appended claims.

In the drawings in which I have shown a substantial embodiment of myinvention, Figure l is an elevation of the basket. Flg. 2 is a plan viewof the flange therein. Fig. 3 is a vertical diametric section of acentrifugal casing, showing one of my baskets in place therein and withthe pulley and shaft of the basket shown in the base of the centrifugalcasing.

In washing clothing and machinery with gasolene and other similarliquids, the liquid soon carries quantities of dirt, metal particles,carbon atoms and other matter, so much so that said liquid cannot beused for like purposes until it has been strained and clarified of suchforeign matter, and such clarifying if at all practical must be donequickly and economically. The present 1nvention is intended for such useand consists of a metal cup-shaped basket A which is mounted for rapidrotation within a casing B. The said basket A to be driven by powerapplied to its axial shaft 1 through the pulley C, but as will beobvious, power for rotating the basket may be applied on or through adepending shaft. The bottom and a portion of the side wall of saidbasket is liquid tight, while the remaining portion of the side wall hasholes or perforations 2 therein. An inwardly turned annular flan e 3 issecured on or to the inner wall of said basket A at or near the loweredge of the perforations 2 in the basket wall. A plural-- ity ofperforations 4 are provided through the said annular flange 3.

The operation of my invention is as follows :With power to rapidlyrotate said basket within its casing B, the liquid to be strained andclarified is poured or allowed to flow through the top of said casing Bby removing its cover 5, into the basket A. Centrifugal motion will beimparted to said liquid and any particles having a specific gravitygreater than the liquid whether soluble or insoluble will be carrieddownwardly by gravity and outwardly b the centrifugal force generatedand W111 accumulate and be deposited in a layer on the bottom andimperforate portion of the side wall of the basket, while the clarifiedliquid will be forced out through the perforations 4 of the annularflange 3 and the perforations 2 of the basket, and will be caught in thelower portion of said casing B and be drawn off through the drain cock 6provided therefor. The operation may be continued if desired until thelayer of waste matter accumulates in suflicient quantities and thicknessa sto stop the perforations 4 of the flange 3, then the basket is to becleaned out. I have found that some deposit of solid matter will befound on the inner wall of said basket above the flange 3, having passedthrough the perforation 4 of the flange, and I therefore continue theseparation above the flange 3 by perforating the upper portion of thewall of the basket as shown at 2, and particularly coloring matter suchas unburned carbon or soot and discolored light oil will be caughtwithin the basket and above the flange.

I thus provide a new and novel centrifugal basket improved for the newuse of clarifying liquids, and by closing the perforations commonlyfound in the lower portions of the wall of such baskets, and also byproviding an inwardly turned annular flange to be rotated with and bythe basket.

Having described my invention I desire to secure by Letters Patent andclaim 1. In a centrifugal basket the combination with a stationarycasing of a cup-shaped metal basket having perforation in the upperportion of its side wall; and a flange member secured onthe inner wallof said basket adjacent the lower of said perforatlons 2. In acentrifugal basket the comblnation with a casing; a closure therefor; acupshaped metal basket having perforation 1n the upper portion of itsside wall; an an-l nular flange haying perforations therein and which isfastened in said basket adjacent the bottom row of perforation in thewall of said basket; and means'to rotate said basket on its verticalaxis.

3. A centrifugal basket for clarifying liquids comprising a cup-sha edmember having its upper portion per orated; and an inwardly turnedflange therein having perforation in the inturned portion; with means torotate said basket within a casing.

4. In a machine of the class described comrising a stationary casing; acup-shaped asket with the upper portion of its side wall perforated andmounted for rotation in said casing; means to drain said casing; an inwardly perforated flange member at the bottom of the perforations ofsaid casing; and means to rotate said basket within said casing for thepurposes described.

In testimony whereof I have aflixed my signature.
